Something About The King

We know that computers are generally classified into four types :

Micro (which includes our PC),Mini,Mainframe and finally
the Super Computers.

We can say Super Computers,the king among the computers in which thousands of processors are linked together to form the most powerful system.

Here I wish to list some of the top Super Computers used now-a-days in this World.

1.BlueGene/L DD2 Beta-System (IBM)- with a speed of 70.7 TFLOPS (tera or trillion floating point instructions per second).This is the most powerful Super Computer used now.

2.Columbia (NASA) - with a speed of 51.9 TFLOPS,consisting of 10,240 Intel Itanium 2 processors.

3.Earth Simulated (NEC)- with a speed of 40 TFLOPS and is situated in Japan.

4.Mare Nostrum - with a speed of 40 TFLOPS and is used in the Technical University of Barcelona.

5.Thunder - with a speed of 19.9 TFLOPS,consisting of 1,024 nodes,each holding four Intel Itanium 4 processors,each running at 1.4 GHz.It is used in Lawrence Livermore National Laboratory.

6.ASCI Q - The Q Super computing system is the most recent component of the Advanced Simulation and Computing (ASCI) Program.It works with a speed of 13.9 TFLOPS ,consisting of 1,024 nodes, each holding four Alpha 21264 EV-68 proessors.It is used in Los Alamos National Laboratory.

:-just for reference,the processing power of the most powerful PC will only be about 5 GFLOPS (G-giga).

No Super Computer from India has taken part in the list so far.

I think we will rise soon and compete with rest of them in the World.
